TO ALL WI-IOM ITMAY CONGERN:

Be it known that I, JOHN BEAN, of Hudson, in the county of Lenawee, and State of' Michigan, have invented certainl new and useful improvements in Pumps and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,` and to the letters of reference marked thereon. v

In the annexed drawings, A represents the pump stock, which is provided, a portion of its length, with u. glass lining, II, forminga chamber for the sucker to worl; in. Bvrepescnts a lower section of the stock, being formed so as to pass into the lower end of the main stock, and provided with a shoulder which allows `it togo in only a certain distance. Between the upper end of this section, B, and the lower'end of the lining is a. metallic plate, I", which is provided with a hole through its centre, through which passes a pipe, E, and also with holes near its periphery, which, in' connection with the leather disk m, lying immediately over them, serve Yto form valves for allowing water to pass up into the chamber x. C represents a metallic boii, which consists of two cups, onemade a little smaller than the other, so that, one being placed in the other, they form abox, with aclose top and bottom until proper openings are made in them for the passage of water. A pipe, D, passes down, and has its lower end secured in the top of this box, and theV pipe `E passes up, and has its upper end secured in the betteln` ofthe bon. g represents a partition, which divides the box into'two parts. a represents an opening inthe bottom of the box, which allows water to pass into it from chamber z. 4represents a leather plate, which lies in the bottom ot' the box, forming two valves, one for the opening a, and the other for the top of pipe E. d represents a metallic perforated plate, which is secured in .the lining H near its upper end. This plate is covered by a leather disk, forming valves for the perfor-ations, so as to allow water to pass up through said perforations, but not downagain. This plate is also provided with/a hole at its centre, in which the pipe D tits so as to slide easily up and down. e representspaeking at the upper end of the lining H. The box (l is surrounded with suitable packing to make it tit snugly in the lining H. Y

In using this pump, the box YC with its pipes is pusheddown asfar as it will go in the chamber O by means of the pump-rod Gr, and, as it draws up again in said chamber, the -water follows it into chamber 9:. As it is pushed down (that is, the box,) the water also passes up pipe E, and through valvegz'into chamber O in the direction of arrow 2. When the box is pushed down again the water in chamber :s is forced up through valve at a, and in the direction of arrow 1, up pipe D, and thence into the chamberabove plate d. The water in chamber 0, as the box works up, is forced through the valves of plate d. It will be seen thatV there are two sets of valves in this pn'mp. The valves of plate F work in. connection with valve at a in the bottom of the box C, and the valve at z' works in connection with the valves of, plate d. The water from chamber a: passes up through valve e and through pipe D, while the water from pipe E and chamber O passes up through'plated.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The box C, constructed as described, and-provided with the pipes E and D, substantially as and for the purpose specified. i

2. The box C with itspipes, when used in combination with the valve-plates F andd, substantially as and for the purpose specified. Y i

p As evidence that I claim the foregoing, I have hereunto set my hand in the presence of ltwo witnesses.

JOHN BEAN.,
